COCK, FAUCET, aoc.

SPECIFICATION forming part of Letters Patent No. 243,118, dated Junel21, 1881. Appnoation filed November 29, 1880. (No model.)

To all whomt may concern Be it known that I, ROBERT P. GAEsED, a citizenof the United States; residing at Norristown, in the county ofMontgomery and State of Pennsylvania, have invented a new and usefulImprovement in Cocks, Faucets, Valves, &c., which improvement is fullyset forth in the following specification and accompanying drawings, inwhich- Figure l is a longitudinal veitical section Fig. 2 is alongitudinal vertical section of a valve embodying my invention. Fig. -3is a view of a detached portion thereof. Fig. 4 is a side elevation of amodification ofthe valvular thimble embodying my invention.

Similar letters of reference indicate corresponding parts in the severalfigures.

My invention consists of the stem of the cock, having at its lower end ashoulder whereby the base of the valve is presented true to its seat.

lt also consists of the expansible valve having a ilange at top which isclamped by the screw-cap, and preventing shifting inwardly by the collarwithin the valve continuous of said cap. g

It also consists of a combination of parts forming an improvement incocks.

It also consists of an expansible valve of the form of a thimble, thebody whereofl is ot' elastic material, and the base of hard materialintegral with said body and closed or imperforate, whereby thewearingsnri'ace of the base is strong and durable.

lt also consists of means for preventing leakage between the valve andsurrounding wall.

Referring to the drawings, A represents a cock or valve, having aninlet-branch, a, an outlet branch or spout, b, a valveseat, c, ascrew-stein or plunger, d, and a branch, c, receiving said stem orplunger and sustaining the screw-cap f.

From the upper edge ofthe branch e is suspended a thimble or tubularvalve, B, formed of soft rubber or other elastic material, having a topflange, g, which sets on the edge of the branch and is clamped by thecap f, and a closed bottom, h, the latter (and contiguous portion, ifdesired) being formed of inelastic, hard, or vulcanized materialproperly connected to the remaining portion of the valve.

On the bottom h of the valve B is placed a button, G, of metal or otherhard material, formed. with a concavity to receive the convex or roundedend of the stem d or convexity when said end is depressed or concave forcentering purposes. The lower end of the stem d (see Fig. l) has ashoulder, which is adapted to abut against the flat portion ofthe upperface of the button C, which surrounds the central concavity or convexityof said button, whereby, while the poi-nt of the stem centers itself onthe button, the shoulder of the stem, bearing against the button,servesto right the latter should there be any irregular motion orposition other than one truly right-angular to the valveoseat, and thusthe base of the valve B is presented true to the valve-seat. Thedownwardextension f is integral with the cap f, and forms an enlargedguiding-surface for the stem d; and as the cap f is immovable when inposition the said extensionf' is likewise immovable, and so the rotationof the stem imparts no movement to the extension f', whereby there is notwisting of the tubular valve B.

On the periphery of the thimble B is a pro o jectin g ledge, It, which,when the valve is open,

is adapted to abut against a shoulder or ledge, 7c', projecting from theinner face .of the branch e. The part f of the cap through whichthe stemd passes is of length to reach the inside of the thimble or valve B, ata point near the ledge lc, in order to hold the flange gin position andassist in keeping the ledge 7c against the ledge k.

The operation is as follows: When the valve l is opened, as in Fig. 1,and is to be closed, the stem d is rotated so as to descend and therebypress against the button C and expand or `stretch the thimble B, thusforcing the base of the latter against the valve-seat, said buttonpreventing the stem injuring the bottom h of the thimble. When the valveis to be opened the stem d is rotated so as to rise; and the thimble,owing to its elasticity, and uncontrolled by the stem d, contracts andso leaves the valve-seat, whereby the latter is un- IOO f, thisprovision of the thimble also obviating paekin g for the stem or plungerd.

When the valve is used for steam purposes the ledge k', Fig. l, may bedispensed with, and in lieu thereof I in ay employ a metallic thimble,7c', Fig. 2, which is interposed between the elastic thimble B andbranch e, and provided with a J lange at top, which is clamped to theflange by the cap; but the ledge 7c abuts against the bottom edge ofsaid thimble 7c and operates similar to that hereinbefore described.

The employment of the thimble k facilitates the displacement ot' thethimble B, as the former may be readily removed with the latter from thebranch e.

The thirnble B may be of cylindrical, conical, or other suitable hollowform.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The cock, &e., provided with the elastic valve B, the loose button C,and the stem d, the

latter having a rounded and shouldered lower end, substantially as andfor the purpose set forth.

2. rlhe eapf, having a downward extension, f', integral with it, incombination with the suspended tubular valve B, formed with a top iiange, g, and the branch e of the cock, whereby said ilange is clamped tothe branch and prevented from shifting inwardly by the eX- tension j",substantially as and for the purpose set forth. n

3. The expansible val-ve B, with liange g, loose button'C, with roundedtop and flat bottom7 cap f, with downward extension f', andvoperatingstem combined and arranged as' described, for the purpose setforth.

et. rllie thimble or tubular Valve B, having a body formed of softelastic material, and an imperforate bottom, h, of inelasticmaterial,integral with said body, substantially as and for the purpose set forth.

5. The expansible valve B, with ledge k, and the branch c, with abutment7c', substantially as and for the purpose set forth.
